Maybe giving a price range would be of some help. Now owning a Nikon D800, looking back down the Nikon range shows how different versions are. Even my D300 doesn't come anywhere near as good photo wise to the D800. I have the Nikon 50mm f1.4 lens and it is ok for what it is intended for but I prefer my Nikon 24-70mm f2.8 as it gives more flexability in its use
